IMPROVEMENT lN INSECT-DESTROYER S.

Specification forming part of Letters Patent No. 216,679., dated June17, 1879; application filed March 24, 1879.

To all whom 'it may concern:

Be it known that I, GEORGE HENRY HULL, of Montello, in the county ofMarquette and State of Wisconsin, have invented a new and usefulImprovement in Insect-Destroyers, of which the following is aspecification.

My invention is particularly intended for use in applying liquid topotato-vines for the purpose of destroying the insect known as theColorado beetle or potato-bug, but it is also applicable to othersimilar purposes.

The invention consists in a novel construction of a syringe andreservoir combined and used in connection therewith, whereby provisionis made for carrying a quantity of liquid for the supply of the syringeand constantly feeding it thereto, and for insuring the proper operationof the syringe in discharging the liquid.

The accompanying drawing represents a central longitudinal sectionalview of an apparatus constructed according to my inven- 'tion.

The syringe consists of a tube, A, provided at one end with a fine rose,B, and a piston or plunger, G, having its rod D provided with a handle,d. The rod passes through a cap, 0,

which fits on the upper end of the tube A.

with a hopper or funnel, f it may be supplied with the liquid to beapplied to the plants.

The tube A communicates with the reservoir G by means of perforations hin said tube near the point where it passes through the lower end of thereservoir.

If desired, the apparatus may be provided with a strap passed through a1001),}, attached to the reservoir, and thus may be carried with moreease, especially when made large and heavy.

The apparatus thus constructed may be used for applying paris-green orany other suitable substance which may be dissolved ill-OI mixed withwater or other liquid.

The operation is as follows: When the piston or plunger is drawn up, theliquid flows through the perforations h into the tube A, and when thepiston is pushed in the liquid is expelled through the rose B in theform of spray, which spreads completely over the vines and destroys theinsects thereon. f

Having thus described my invention, I claim as new and desire to secureby LettersPatent The combination, with reservoir G, of the central tube,A, extending through reser voir, having rose B at lower end, connectingby perforations with the reservoir, and provided with a piston thatworks down to the rose, as shown and described, whereby the fluid isforced downwardly and directly upon the plants, notwithstanding thewind, all valves are dispensed with, and the danger of clogging the rosewith the paris-green is entirely prevented.
